Vim’s too long string invalidates the highlighted portion of the code

  question, vim

As shown in the figure, the code highlighting in front is still normal, and the code highlighting in the back starts from white, and VIM’s automatic indentation also fails. How do you do it?

This is how it is written

$links = array (
 "www.example.com/path/to/sw" ,
 "www.example1.com/path/to/sw" ,
 //   ...
 );
